TUEBINGEN, June 16, 2003 (LifeSiteNews.com) - A study by researchers at the University of Tuebingen in Germany has found that anal sex, both homosexual and heterosexual, is the second largest cause of HIV transmission in Africa. Transmission in medical settings, such as through dirty needles, is listed as the primary cause, says the study published in the current edition of The Journal of Sexually Transmitted Diseases and Aids.  In a finding which has HIV/AIDS activists on edge, the researchers, say vaginal transmission of HIV is a very distant third compared to medical transmission and transmission through anal sex.  The report’s author Dr. Stuart Brody, of the Institute of Medical Psychology and Behavioural Neurobiology, said people in Africa need to be told that anal sex poses a greater risk of transmitting the Aids virus.  See BBC coverage:  http://news.bbc.co.uk/2/hi/africa/2993016.stm
